Also, Sherlock a sociopath? Really? He's indifferent at worst. Certainly not hostile to the average person most of the time. "Failure to conform to social norms" is one of the criteria for diagnosis as having antisocial personality disorder. At the least there's a lot of imposition of social norms mixed into the diagnostic criteria for all those "disorders"

Well, that's what the series said in the first episode, and maybe the second too. I think he does come off as a little sociopathic, minus all the malevolent parts - schizoid doesn't seem to imply the manipulation or game-playing which all good Sherlocks engage in (whether they're named 'Sherlock' or 'House').
